2 Claims.

My invention relates to haircurlers and is particularly directed to haircurlers which initially support a hair pin and which efiect anengagement between the hair pin and a curl of hair formedaround amandrel of the curler. A hair curler of this type is shown in U. S.Patent No. 2,321,931 of June 15, 1943, to Victor M. Newman.

In curlers of this type, means should be provided on the curler tofirmlyretain the hair pin so that displacement thereof is avoided while thecurler elements are manipulated toform the curl.

Such'firm retention is also required when the engagement between theformed curl .and the hairpin is effected ,as otherwise the engagementmay be incomplete or generally unsatisfactory. However, in attainingthiszobjective, it is dcsirable'to avoid limiting the utilityof thecurler to a-specific type .or size of hair pin since a wide variety ofhair pins are conventionallyusediat present.

With the foregoing in mind, an object of this invention is to increasethe ,utility of such a curler by permitting the utilization of hair pinsof varied sizes and :shapes Without sacrificing the required firmnessfretention referred to above. Another-object of this invention :i :toprovide an efiicient hair in retaining structure which shall spread-thhair pin to anextent where its engagementwitha curl is rendered'morepositive particularly in respect to .larger'curls and stray hairs.

Another ohjectof this-invention is to simplify the operatingprocedure informing curls while producing acurler of extreme structural simplicityin which onsiderable manufacturing economies are realized.

Another-object of this invention is to provide improved means fordisassociating the formed and pinned curl from'the. curler.

Other objectsof my invention will be apparent from the followingdescription it being understood that the above general statements of theobjects of my ,invention'are intended-toexplain and not-to limit itinany manner.

The support l0 and mandrel member Il may be integral and may be formedof wood, plastic, metal, etc. The support I0 also functions as a 2.handhold member and is formed with a longitudinal groove l2 in which isdisposed the wire l3. The wire 13 extends the length of groove l2 and isbent over and secured to the housing It at l4.

Telescoped over the wire l3 for sliding longitudinal movement in thegroove I2 is the hollow hair pin carrier 15 which also functions as aclamp, retaining a lock ofhair between itself and the mandrel member l;lin the initial step of the curling operation.

The hollow hair pin carrier i5 is bent upwardly to form a manualoperating member It by which the hair pin carrier I5 can be slid overthe wire l3-in its telescoping action. In order to permit such action,the hair pin carrier I 5 is formed with an. opening I! through-which theWire I 3 enters the hollow of the hair pin carrier. The mandrel member His formed with a longitudinally extending concavity i=8 whichcommunicates with the slot I 2 thus providing a continuous path for thehair pin carrier l5.

The hair pin carrier [5 is tubular as seen in Fig. 4 and an arcuatesection of its outer end is cut away to form a hair pin gripping tongueIt). This hair pin gripping tongue includes the hump 2|] formedby'bending the tongue l9, and the downwardly biased tip 2|. Thus, thetongue I9 is substantially L-shaped by being bent in two directions, thehump 20 terminating one angle leg of the L While the tip 2-! constitutesthe other angle leg. It will further be noted that the tongue is ofsufficiently small size and extent. as to besubstantially confined tothe closed end of thehair pin. This not only permits wider opening ofthe hair pin but permits almost the entire hair pin to receive thecurl.v Tongue l9 cooperates With the cut edge 22 of the carrier l5 ingripping the hair pin 23. The hair pin which is of the conventionalsubstantially U-shaped construction has its lower leg 24 gripped betweenthe tip 2| and the cut edge 22 thus relieving the tubular portion of thecarrier l5 of this function. Accordingly'the leg 24 is accorded the fulldiameter of the comparatively substantially wider carrier 15 as seen inFig. 4, so that the thickness of the leg 24, or the fact that it mayassume various shapes does not prevent its being received .by thecarrier l5. The edge 22 bears against one .point of leg 24 and therebyurges the leg against the opposite wall of the carrier {5. Thus plastichairpins which are ordinarily thicker than metal hairpins can beaccommodated. Additional retention plus spreading of the hair pin isefiected by the tip 2| which coacts-with thehump-EU in interposing aneffective wedge betweenthe 18g 24 and the leg 25 of the hair pin. Itwill be observed that this wedge is disposed adjacent to the junction ofthe legs 24 and 25 so that the angle of spread is considerablyincreased. The downwardly biasedtip 2| acts in opposition to the hump 20in eflecting the wedging action. With the: foregoing construction, itmay be considered that the hair pin is held at 4 places, viz., the majorposition of the leg 4 frictionally abutting the inner wall of thetubular carrier i5, the pressure of the cut edge 22 against the leg 24,the pressure of the tip 2| adjacent the junction of the legs 24 and 25,and the hump 20 acting in opposition thereto. The pressure at thesedistributed points avoids the necessity of a gripping elementspecifically shaped to fit the legs of the hair pin.

The mandrel H is little more than semicircular in cross section asillustrated in Fig. 5, but at the inner end thereof its sides rise, asseen in Figs. 1 and 2, so that its overall thickness at the pointadjacent the wire (3 is increased accordingly, One of the purposes ofthis increase in thickness is to prevent the formed curl fromaccompanying the hair pin carrier as it recedes into the groove l2 ofthe support I!) since the curl will have been formed around the lesserthickness of the mandrel member H and its internal diameter willtherefore be such as to prevent it riding over the portion of increasedthickness.

A ring 26 is slid over to mandrel member H and, making frictionalcontact with the larger diameter of support 10, serves to complete theassembly of the device and to prevent the complete disassociation of thehair pin carrier l from the telescoped wire I3 as seen in Figs. 1 andThe simplicity of assembly of the instant device is notable. The wire I3is initially inserted in place. The hair pin carrier i5 is then slid infrom the opposite end until the opening I! causes it to telescope thewire l3. The ring 26, which may be of metal, rubber or the like, is thenslid over the mandrel member to the support where it is' frictionallyretained, completing the assembly.

My invention is practiced in the following manner:

The hair pin is applied to the mandrel memher by inserting its leg 24into the outer end of the tubular hair pin carrier l5 whereupon theabove mentioned gripping elements take effect. A look of hair is thenapplied between the hair pin carrier I5 and the mandrel member II whereit is retained due to the tendency of the carrier IE to maintain itsposition in the concavity l8. The device is then rotated so as to form acurl 21 around carrier l5 and mandrel member. The operating member I6 isthen rearwardly actuated by'the fingers thereby retracting the carrierl5 and the hair pin. This retraction continues until the hair pin iscaused to embrace the curl 27.

During this retraction, the leg 24 of the hair pin is carried toward thewire I3 due to the telescoping action of the carrier l5 and said wire.When it approaches the groove l2 it will meet the stationary wire [3 asillustrated by the dotted lines of Fig. 3 so as to prevent furthermovement of the hair pin. Continued retraction of the carrier [5,therefore, necessarily disassociates the hair pin from the carriergripping elements and effectively frees the formed and pinned curl. Anytendency of the curl 21 to enter the groove I2 is resisted by theincreased diameter of support l0 at that point so that the formed curlis effectively prevented from entering the support and to this extent,the increased diameter cooperates with the wire l3, each jointly servingto resist the continued movement of the respective hair pin and curl.This expedient further serves to maintain the degree of engagementbetween the hair pin and the curl during the ejection of the pinned curlfrom the curler.

During the retraction of the carrier, and after the tongue l9 leaves theclosed end of the hair pin, the movement of the hair pin is confined toa straight path since it is guided by and rides in the concavity l8 ofthe mandrel member. Thus it cannot swerve so as to distort the curl orinterfere with its proper pinning. When the carrier I5 is finallyretracted, the hair pin is still in the concavity I8 and its lower legis loosely held by the tongue l9 as illustrated in Fig. 3. This insurescontrol of the curl at all times during its formation and pinning.

I have shown a preferred embodiment of my invention but it is obviousthat numerous changes and omissions may be made without departure fromits spirit.
